Dr. Gwen Adshead, a forensic psychiatrist with nearly four decades of experience, delves into the intricate nature of violence in her Reith Lectures. Drawing from her work within secure psychiatric units and prisons, she explores whether violence is an inherent part of human nature or if it arises from specific circumstances. Through real-life stories and data, she examines the factors that lead individuals to commit violent acts and discusses potential solutions to reduce violence in society.
